Feature: 1. When the protected circuit enters an unsafe value, the built‑in protector automatically cuts off the circuit, and resumes normal operation when the value returns to the normal range. Possess automatic protection functions such as overcurrent, overvoltage, overheating, short circuit, etc. 2. Boost converter is designed with potting and waterproof technology, bring all‑round protection, more stable and reliable 3. Adopt organic silica gel potting, has waterproof, dustproof and shockproof effects, so that suitable for use in various harsh environments 4. This voltage regulator can be used for LED car display, surveillance camera, electric fan, water pump, motor, photovoltaic energy numerical control equipment, water pump, router, ADSL modems, switches 5. Suitable for LED lights, digital photo frames, electronic refrigerators, portable DVDs, stereos, security systems, portable tools, printers, network equipment, various industrial electrical equipment with corresponding voltages, etc. Specification: Item Type: DC Voltage Regulator Material: Organic silica gel + aluminum Model: GYVRM-CDL124810 Input Voltage Range: 12V (DC10-20V) Output Voltage: 48V Rated Output Current: 10A Output Power: 480W Protection Level: IP67 Conversion Efficiency: Up to 96% Working Temperature: -20℃~+80℃ . Package List: 1 x DC Voltage Regulator1 x Wiring Drawing Note: 1. In order to ensure the normal operation of the converter within the input voltage range, the input voltage must not be lower than the minimum or maximum input value restricted by the product during use, and the input voltage value must be higher than the output voltage value by more than 2V. If there is no voltage difference of 2v, the output value will be lower, but it will not damage (affect) the use of the converter.2. The input current must be greater than or equal to the required power of the output load device (for example, if the power of the load device needs 100w, then the input power must be greater than or equal to 100w). When the converter is in use, the current of the load device should not be greater than the maximum current value that the converter can withstand, and leave as much margin as possible for the converter to ensure that the converter works normally and achieves the highest conversion efficiency.3. The positive and negative poles of the converter cannot be reversely connected during use. Reverse connection may cause damage to the converter. It is recommended to add a suitable fuse to the input terminal during use.4. When there is no load, the chip works in light load mode, and the output voltage may vary within a certain range.5.Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
